First of all,
for AS physics
Q.a object is thrown 30degrees from the horizontal ground under the condition:no upthrust,no air resistance
gives a parabolic path.
By this,
Does the object have constant velocity?
If the answer is Yes,it has constant velocity,
isn't it wrong to say that the velocity of the object at the highest point is
ucos30degree?
because cos30 is 0.5 so the velocity becomes half of the initial velocity
For AS Mathematics Statistics1
If the question ask to draw a cumulative frequency graph,
when are we supposed draw a straight line or a smooth curve??
I know that for the question asking a polygon, its a straight line
and a curve, its a curve
but just asking for a graph, i don't know what to draw
And Lastly,
i know length is continuous
what about for
marks discrete or continuous?
hours discrete or continuous?
speed?
Please help me..
